Abstract

There is currently a high activity in the transportation tunnelling industry in the countries of the European Union with the highest seismicity. In this work, and in order to assure the safety of vulnerable tunnel cross-sections or cross-sections where very high standards of safety are required, an integrated package is being developed that includes a deformation monitoring system that can provide real-time measurements of tunnel deformation during an earthquake and a decision support system that processes these measurements to assess the lining's ability to survive expected aftershocks.
